It seems like maybe the problem is that automakers were able to widely market vehicles that use wireless protocols that are relatively easy targets for attack. This was never properly secure.

Automakers should absolutely be held to higher standards (in general) than they are, and it's not likely that banning specific devices is going to have any measurable outcome here. It's pretty well known that people buy and sell malware, and people can just... make devices similar to a Flipper with cheaply and readily available hardware.

This is just dumb posturing to avoid holding automakers and tech companies accountable for yet another dumb, poorly thought out, design feature.

And obviously it doesn't stop at cars. It seems pretty clear that snooping on any feature using RFID or NFC tech is only going to become more widespread. Novel idea: what about using... actual keys as the primary method of granting physical access? Lock picking is obviously possible but a properly laid out disc-detainer lock is pretty goddamn hard to bypass even with the proper tools, and that skill can't just be acquired in the same way as with electronic methods of bypass.
